Question

A soccer stadium in Portland has a total of 728 seats spread over 28 rows. How many seats do 12 rows in the stadium accommodate?

Answer 1

total seats spread is 728

no of rows is 28

i.e 28 rows will give 728 seat spreads

1 row will give x seat spread

28------- 728

1--------- x

cross multiplication

728 x 1 = 28 * x

728 = 28x

divide both sides by 28

728 / 28 = 28x/28

x = 26 seat spreads

1 row will give 26 seat spreads

for 12 rows we have 12 x 26

= 312 seats spread

12 rows will accommodate 312 seats
